The D spec says private member functions are not virtual. Not that I 
agree with it, but it's like this.

"All non-static non-private non-template member functions are virtual."
<http://www.digitalmars.com/d/2.0/function.html>

The worst part of it is that changing a function from private to 
public, or the reverse, is a breaking ABI change because it affects the 
vtable.
